Acute Heart Failure During the Peripartum Period Due to Aggravated Tricuspid Regurgitation.

Latent valvular heart disease may be aggravated or demasked during pregnancy because of physiologic hemodynamic changes, including higher circulating volume, heart rate, and cardiac index, as well as stress during labor. The presence of valvular heart disease increases the risk of maternal and fetal/newborn adverse events. Early diagnosis, risk assessment, and specific management are crucial. We present a case of acute peripartal heart failure caused by idiopathic severe tricuspid regurgitation in a 38-year-old woman.
